CLAMP.

SPECIFICATION forming part of Letters Patent No. 710,049, dated September 30, 1902.

Application filed January 27, 1902. Serial No. 91,369. (No model.)

To all whom, it nuty concern:

Beit known that I, SEELE HOWARD ELLIS, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, city of New York, and State of New York, have invented certain new and useful Improvements in Clamps, of which the following .is a specification, reference being had therein to the accompanying drawings.

This invention relates to clamps, and a clamp embodying my invention is particularly adapted for clamping heavy parts upon a tubular supportas, for example, an engine or motor upon a bicycle-frame.

My invention has for its object to provide means for exerting a very considerable clam ping pressure u pon a tubularsupport,suffieient to permit the clamp to sustain a heavy Weight and sharp concussions and'vibrations without distortion or collapse of the tubular support.

I will now describe the clamp embodying my invention illustrated in the accompanying drawings and will thereafter point out my invention in claims.

Figure 1 is a side elevation of a clamp embodying my invention, showing the same clamped upon a tubular cylindrical support. Fig. 2 is avertical central section of the same. Fig. 3 is a plan of the clamp with the support in section.

The tubular support 1 may be any part 0 l the frame of a bicycle or railway-inspection car or other structure in which tubular construction is employed.

The part of the clamp which is in actual contact with the support comprises a longitudinally-divided sleeve of considerable length and shaped to conform to the support, so that when tightly clamped upon the support this sleeve distributes the clamping pressure over a very considerable surface and, in fact, stiffens and strengthens the tubular support. In the construction shown the longitudinal sleeve is divided into tWo nearly semicylindrical parts 2 and 3. One of the parts of the sleeve the part 2carries the attaching means for engagement with the device to be supported, such attaching means comprising a cross-bar 4 and lugs 5, the cross-bar 4 being brazed or otherwise secured to or formed as shown fitted upon the part sleeve 2, and I terminating at each end in a screw-threaded stem 8, the band as a whole being U-shaped. These bands cooperate with caps 9, with which the screw-threaded stems engage by means of nuts 10, each cap bearing upon the part sleeve opposite to the part upon which its corresponding band 7 bears, and each cap having a flat bearing-surface and having an angular flange conforming at its edges to the cylindrical surface of the part sleeve.

This clamping device is of simple construction and highly efiective in operation. The bands 7 and caps 9 distribute their clamping pressure over a considerable surface of the part sleeves and the part sleeves distribute their pressure over their full length. Each of the parts of the clamp cooperates with the other parts to stiffen and strengthen the structure as a whole.

It is obvious that modifications may be made in the construction above particularly described within the spirit and scope of my invention.

Whatl claim as my invention, and desire to secure by Letters Patent, is-

l. A clamp comprising an elongated sleeve divided longitudinallyinto parts, a plurality of clamping-yokes at different points along the length of such sleeve and bearing upon such sleeve to clamp the parts thereof upon a support, and attaching means for engagement with the device to be supported, such attaching means being carried by one of the parts of the sleeve.

2. A clamp comprising an elongated sleeve divided longitudinally into two parts, a plu rality of clamping-yokes each having a band bearing upon one of such parts and a cap engaging With such band and bearing upon the other of such parts, and lugs for attachment to the device to be supported or carried by one of the parts of the sleeve.

3. A clamp comprising an elongated sleeve divided longitudinally into two parts, a crossbar and lugs for attachment to the part to be supported medially carried byone of the parts of the sleeve, two clam ping-yokes, one at each side of the attaching-lugs and between the attaching-lugs and the end of the sleeve, each clamping-yoke having a band bearing upon one of the parts of the sleeve and a cap engaging with the band and bearing upon the other part of the sleeve.

4. A clamp comprising an elongated sleeve divided longitudinally into parts, a plurality of clamping yokes each comprising a U- shaped band having a bearing-surface upon such sleeve conforming thereto and also comprising a cap engaging with such band and bearing upon the sleeve oppositely to the band, and attaching means for engagement with the device to be supported, such attaching means being carried by one of the parts of the sleeve.

5. In a clamp, the combination of the part sleeves 2 and 3, the crossbar tand lugs 55ecured to the part sleeve 2, the braces 6 be.- tween the cross-bar and part sleeve, and the clamping-yokes each comprising the U- shaped band 7 having a bearing-surface upon the sleeve conforming thereto and also comprising a cap 9 bearing upon the sleeve oppositely to the band, each U -shaped band 7 having ends engaged by clamping means with the cap of the corresponding yoke, substantially as set forth.

In testimony whereof I have affixed my signature. in presence of two witnesses.

SEELE HOWARD ELLIS.
